.Ths invention relates to binder-twine boxes to prevent the ball from collapsing and/or as fitted to harvesting machines such as mowentangling. ing machines, threshing machines and the In order that my invention may be well unlike. Such a box is ordinarily adapted to derstood, I shall now proceed to describe the contain two binder-twine balls placed the same with reference to the annexed drawings, 5

This pressure 7 in view I suggest to provide the box with will prevent the upper ball from collapsing means adapted to exert a resilient pressure and from being drawn against the cover I), externally on a ball placed therein so as to when said ball has forthe greater part been keep it in the proper shape when unwinding, unwound. I :0 to counteract its tendency to be pulled up by When ball 0 has been completely wound the tension occasioned by the binder, and also oif, box a is uncovered and shell d containing 1 no ball is removed therefrom. Thereafter, ball is removed from the shell and its outer end knotted to the leading end of a fresh ball, whereupon both balls are reinserted into the shell, the fresh ball down, the shell again placed into the box a and the cover I) put in place.

In order that the ball or balls within the shell cl may easily be removed therefrom, the latter may be provided with one or more longitudinal slots p, through which the attendant can insert his fingers to engage the balls and push them axiall out of the shell.

In Fig. 3, which illustrates another embodiment of my invention, box a has not been shown. According to this figure, a plurality of equally spaced spring blades 0 parallel to the axis are secured at either end to the inner wall of shell (Z, the radial distance between two diametrically o-pposed blades nor mally. being slightly smaller than the outer diameter of a ball. Also in this case the spring blades. rmay be so, arranged as to exert a greater amountof pressure on. the upper ball than on the lower ball.-

According to Fig. 4, in which box a has also been omitted, the cover his provided with a cylindrical extension 8,. which now performs the function ofthe loose shell cl in the embodiments described above. The axial lengthof the extension 8 is almost equal to that of the box a, into, which it is to be placed. Its upper half is provided with. a plurality of=axial, inwardly curved spring blades 1 cutout of thematerial andthe lower half has a plurality of long, axial recesses forming between them a plurality; of inwardly curved spring blades .1" having offset lower portionst, lockingring 1; being slipped over said blades 0". If the upper ball 10 placed within this cover has been entirely wound oil, it is not. necessary to remove the lower ball 70 from the cover, but the same cansimply be pushed into the upper portion of. the .cover, after its outer end has been knotted topthe leading or inner end of a freshball; which, is then inserted into the cover from-.below, ring 1: assuming itscentral position; Thereafter, ring o is slipped downward over springs r, whereby the clutches t of these springs are pressed inward s0,-as-to lock ball In. p

In Figs. 5 and 6, thebox .a has a lidyw hinged thereto as at m and isprovided with 1 an eye 0. The shell cl is formed by a thin sheet of resilient metal bent into a cylindrical shape, a certain gap being left between the axial edges y,.y edge, the shell (Z is provided with six hooks 2, formed by lips stamped from the sheet and having an inward curve in addition to an outwardly bulged horizontal section, so that they can serve to guide the binder twine-balls to be inserted into the shell. The. shell d 1s suspended by its hooks 2 from the top edge Along its top of the box a. This embodiment has the advantage that the outer diameter of the shell needs hardly be smaller than the inner diameter of the box, although the shell is provided with efficient guiding means for the twineballs. In Figs. 1 and 2, the flared upper portion of the shell must be accommodated within box a, that is to say, there must be a certain clearance between the cylindrical portion of the shell and the box, so that the latter must be wider than normal in order to receive twine-balls of normal size.

What I claim is 1. In combination, a substantially cylindrical box adapted to contain a binder-twine ball, and a loose split shell of resilient metal placed inside said box and bent into a cylindricatshape. so as to tend to exert external radial pressure upona ball placed in the shell,

said shell. being'provided along its top edge with a plurality of hooks adapted to engage the top edge of thebox.

2.- In combination, a substantially cylindrical box adapted to contain a binder-twine ball, and.' a loose split shell of resilient metal placed inside said box and bent into a cylindrical shape so as to tend to exert external radial pressure upon a ball placed in the shell, said shell being provided along its top edge with a plurality of inwardly curved and in horizontal section bulged hooks adapted to engage the top edgeof the box.

Intestimony whereof I afiix my si nature.
